Connect to gmail-smtp-in.l.google.com Network is unreachable or timed out.

I'm seeing numerous errors in Syslog of Proxmox trying to send emails to me. I'm a home user with the non-enterprise version of Proxmox installed on a NUC. I had this issue a year or so ago when I had Proxmox installed on an older NUC. I've since installed a new instance on a newer NUC. I resolved the problem back then but can't remember how I did it. I see a number of posts about email but am not sure where to start.

Any pointers certainly appreciated.

Network is unreachable or timed out.​

usually indicates a networking issue - sometimes a firewall in front of PMG causes connections to be dropped - maybe this is the case here as well?

I hope this helps!

Thanks for the tip. No firewall except for a DNS blocker (AdGuard Home) on a Raspberry Pi.
